Delayed by 30 minutes....then the crew preboarded a sick lady and her travel companion. At some point crew decided she should not fly to LA, but the ladies wouldn’t get off plane! 45 minutes later and 4 RCMP show up to escort them off plane. Then we didn’t have any ground crew to get us off loading ramp. Finally got away 90 minutes or more after scheduled departure. Circled LA a few times before getting to land.... long flight with long delays!"

Pros: "Nice service and efficient boarding since the plan shed Of us at the terminal was delayed for weather reasons. Tasty food, the wrap was great."

Cons: "Generally announcemect is too fast and not clear, especially the boarding anouncement regarding the order of boarding is not clear. Please be more considerate for the aged and hard of hearing, infrequent traveller."
Cons: "Transferring between distant terminals in LAX was a pain. I'm glad that I had a long layover between flights to make the journey that required leaving and re-entering security."

Pros: "Good service easy boarding luggage came out as soon as we were off the plane when you are on vacation last thing you need is to wait for your bags great job all around"

Pros: "Not cold, not noisy aircraft"
Pros: "Planes were clean and crew was polite. Plenty of leg room."
Cons: "I was not able to check online. Their kiosks at the airport were out of order. All of them! All their baggages were being photographed and double tagged. They had to call some where to get me a boarding pass. It seemed like they were doing their best to discourage me, never to fly with WestJet. And they might have just succeeded."
Pros: "Quick and comfortable"
Cons: "No tv but understanding for price of flight"
Cons: "Appalled that I was approached by two flight attendants separately to turn off my light in order to accommodate another passenger as the light was bothering them on a night flight. I pay premium pricing for the Plus seat so I have extra room to work. I chose not to turn off light in order to work, then flight attendants allowed the passenger to approach me. Really unacceptable to put me in uncomfortable interaction, making me play bad cop. I was sitting behind passengers talking loudly who were using profanity. My solution? Earphones. This is a commercial flight - offer passengers eye covers, some solution, or tell them to deal with it, or tell them to charter a private plane. Don’t tell us to sacrifice what we pay for, because you can’t do your job. Lost a loyal customer."
Pros: "The plane wasn't full."
Cons: "The crew was late."
Pros: "I really appreciated the leg room that we had on all our flights. The seating was most comfortable. Staff most friendly."
Pros: "The Crew was excelent, WestJet has the best crew, very courteous and helpful unlike disgruntal AA crew. They also have the best price deals available. I highly recommend this airlines. Thanks"
Cons: "No entertainment unless you buy one of their tablets. Unerstandable given the type of fleets they use."
Pros: "Flight attendants Snacks Entertainment options"
Cons: "No screens; but the options were provided"
Cons: "No TV screens, but there was an alternate"
Pros: "Crew are always pleasant it just gets a bit too hokey!"
Cons: "Calgary airport for a transfer between Canada and the US is like a bad episode of Monty Python! It takes far too long and is far too dependent on the efficiency of silly tram drivers, baggage handlers who are phantoms and computer efficacy! All I care about at the airport, and all I want from airport staff is ruthless efficiency. Anything besides ruthless efficiency is just obnoxious and wastes my time!! No wifi on the aircraft nothing decent to eat on a flight scheduled during the dinner hour"
Cons: "Flight was delayed and took another 45 min to leave once boarding was complete"

No cofee or minimum refreshments

Flight was Scheduled for 4:25PM ET but didn't leave until 8PM ET. Terrible!

I wish this and other airlines would board you by row, starting at the back. This was just the free for all approach. Cabin crew were really really nice and also efficient. Captain kept us updated as needed.

Very spacious. There was no food or entertainment. You could offer at least a soft drink to passengers. It's a long flight.

Checking on line didn’t work

The flight and attendants were very good however if I may suggest that the lead attendant who speaks on the intercom, speaks a bit slower She was talking so fast you could hardly understand what she was saying

System had messed up and people who had purchased specific seats had been placed randomly around the plane. ie. I didnt get the seat I payed for

Flight was on time. Staff were good. The seats did not recline so was very tight. Had to pay for water!

You could not cancel flights, that would be fantastic

I didn’t like that our flight was changed by a full day which left us scrambling for a motel room for 6 people at our own expense when I asked Flair they said because we gave you 24 hours notice we would not be reimbursed

Flight was on time. Landed at Pearson a few minutes early but still waiting for our bags over an hour and a half since landing!!! Horrible baggage handling at Pearson!!

Nice plane

I was not impressed with receiving messages concerning the original time of departure was sent to me as well as the current updated messages for the corrected time of departure. I needed to call and speak with a person to ensure my daughter and I were on the correct flight. It was confirmed however, the correct time of departure was then changed from 4:45 pm to 6:05 pm. Once at the airport, it was then changed to depart at 6:30 pm. This was a 4.5 hr. flight so we arrived at Ottawa International Airport at 1:30 am on June 12th rater than shortly after midnight. There were no refreshments served, with the exception of water. This was not acceptable for this flight. Thankfully my daughter and I were able to have something to eat shortly prior to boarding.

The flight was alright however, the seats did not recline making this 5 hour flight uncomfortable for me. The flight attendants were very nice. The flight itself was very smooth with only a few ripples. It was delayed in leaving but not by much.

Poor customer service. Do not print my ticket on the check in (airport).

Unprofessional in every manner

On time

Normal

They make you pay for everything:- hand carriage, seat, check-in and don't even offer you a cup of water! It turnout much more expensive than AC !

I didn’t like It at all cause of delays and cancellations last minutes? No entertainment not even charging points in plane ..and I noticed when one flight landed from flair’s air plane the reuse that plane which is fine but no safety protection no sanitary nothing .

Flight was late

Brand spanking new planes and amazing crews.

Pros: "cabin crew was friendly enough"
Cons: "The flight was delayed over an hour on the tarmac because an engine wouldn't start!"
Pros: "Great crew, fast boarding, nearly empty plane so I had the whole three seat row to myself."
Cons: "The hydraulic pump for the inboard flaps sounded like it was on it's last legs and howled whenever adjustments were made. The cabin pressurization system whistled so loud that I had to put ear buds in to protect my hearing (just on takeoff/landing). Proper maintenance is important!"
Pros: "Comfortable seat with plenty of hip & leg room."
Cons: "Charged $35. for luggage because I didn't know I could go online with the Flair Air website & pay prior to check in. They were friendly and advised me to do this in the future."
Pros: "The plane didn't crash like website and they did not charge $10 for printing off my boarding pass, as no one could with website down. Also, some budget airlines now only allow 40lbs in checked baggage, Looks like they allow 50lbs."
Cons: "Similar problem on the way home, could not book luggage online but could check in. Shop closes at 5 CST so could not call. Even though we told at checkout that it was because of the Christmas volume online, still had to pay Airport (extra) price to check-in baggage. They said I could perhaps get the penalty fee returned if I called in. Told her it's not worth 2 hours on a paid long distance call to get $20 back."

Pros: "Crew were great."
Cons: "I was told by transat to down load an App. to watch entertainment only to be told by Flair Air that they did not provide the service and that I was given the wrong information. So no TV for 5 hrs."
Cons: "New leaf discontinued their Sunday Halifax to Hamilton flight which was to be my return flight home. They did offer me a full refund if I needed to cancel or to rebook on a different flight but I couldn't make the new dates work so I took the full refund. I booked the flights in December for a flight in Feb and they cancelled half way through January so there wasn't a lot of notice given"
Pros: "Everything about Newleaf was awesome."
